Re: F-Secure Client Security and KB4056892

Hi,

We're currently testing all product/OS configurations to ensure full compatibility with the January 3rd 2018 Windows Update. Once we have concluded our testing, we will release a channel update that creates the ALLOW REGKEY detailed in KB4056892. This update will apply automatically and will not require any user interaction. Once our product update has been released, Windows updates should continue to apply as normal. We estimate that our product update will be pushed out tonight or early tomorrow.

Best Regards

-Ben

Re: F-Secure Client Security and KB4056892

Hi Ben,

I only have a small number of CS 13 clients, as most of my Clients are still CS 12.31, but I can see I now have the registry key on my CS13 systems:- HKEY\Software\Microsoft\Windows\CurrentVersion\QualityCompat

For my ignorance, why does this particular registry key need to be created by F-Secure?

We have been "playing" on some test servers with some of the Microsoft patches just released for Windows 2008 & Windows 2012, & the patches seem to install find WITHOUT the registry key being present.

So the fact the patches have seemed to install ok mean that although the patch has “worked”, could it be that the Anti-Virus software itself could then potentially cause issues?

So when the registry key is there, the Anti-Virus software has also been patched to the right level before the MS patch goes on it, so it should then not cause any issues?

Re: F-Secure Client Security and KB4056892

The update will not be released until it is confirmed compatible. Below is statement from Microsoft website :

If you have not been offered the security update, you may be running incompatible anti-virus software and you should follow up with your software vendor.

Microsoft has been working closely with anti-virus software partners to ensure all customers receive the January Windows security updates as soon as possible.

Re: F-Secure Client Security and KB4056892

Hi,

The update should be released under UltraLight update. Since it is a channel upgrade, it might take sometimes for it to be pushed to all the channels.
